I've fixed a few unpleasant bugs; mainly the bug that introduced various uninitialized variable warnings was bothersome. Now it is possible to do bootstrap with -fsanitize=undefined, even though there are some comparison failures at the end.

One patch is not in yet, but that isn't anything important: http://gcc.gnu.org/ml/gcc-patches/2013-08/msg00376.html Ok to merge ubsan into trunk? Marek
